Hello Guys,
I was looking through the video section of the data sheet and I was wondring if one can get a DAC capability out of the video section in particular the VGA output.· Any thoughts.

    'No reason why not. You could feed the eight bits to a DAC IC, or just use a resistor network. In the latter case, and for a full eight bits, an R-2R network will provide the best accuracy and monotonicity.
